When using a Bunsen burner make sure flammable materials do not surround the burner's area. Make sure you wear safety goggles. After the material has been heated, wait several minutes before grasping it . (BETTER YET, ALWAYS USE GLOVES!) Use beaker tongs, ring stand and wire gauze where required.
Take care to not expose thermometer to flame as this will cause an explosion!
When finished with the burner, turn gas off completely.
General Safety Rules:
Safety goggles must be worn at all times (contact lenses should not be worn).
Long hair must be tied back and loose clothing must be secured.
Do not consume any of the hydrates and other materials used in the experiment.
Gloves must be worn at all times when handling hot materials.
Take extra care when using the heating pad to avoid burning- if skin is burnt, rinse under cold water.
If mercury is spilled from the thermometer, notify a teacher immediately. Do not try to clean it up yourself.
Report all breakages of beakers to the teacher. Broken glassware and glassware with sharp edges must be repaired or disposed of properly. Be sure that all glass splinters are swept up and placed in the broken glass container.
